Hey

I have a QA question from the prac test three from pearson..
I don't know if I'm allowed to post the question, so to be on the safe side, can someone who took that paticular test PM me?

I dont fully understand the explanation to the question about the density of water.

Thank you so much!

I'm assuming you are talking about question 30. If you are, the answer is B because you want a low standard deviation and a high number of samples. If that doesn't make sense you need to google things like "statistics" or "standard deviation" or "sample size."
